I. INTRODUCTION

       1. Shipping accidents

Shipping is fundamental as well as dominant means of transport for the world trade 1 as
the Earth is almost covered by sea. Nearly 90.000 vessels of various sizes and more than
250 different types, specialized on cargo or passenger trade or both, serve for humanity.
(O’Neil, 2003)

Ships trade in a high-risk operating environment. In the age of precision navigation and
the satellite era, very many casualties still occur at sea. Even the available advanced and
sophisticated navigation instruments and the enhanced communication technologies have
been unable to halt shipping accidents.2 Shipping is and always will be full of risks despite
high and ever increasing safety standards.

The Oxford English Dictionary defines an accident as, “anything that happens without
foresight and expectation: an unusual event, which proceeds from unknown cause, or is an
unusual effect of a known cause.”

Webster’s Third New International Dictionary gives the similar essence - but with slightly
more explanation, as “a usually sudden event or change, occurring without intent or
volition through carelessness, unawareness, ignorance, or combination of causes and
producing an unfortunate result.”

Shipping accident is a term generally used for any accident results in financial loss, either
in life or property or both. (Akten, 1982)

Any shipping accident, whatever in nature, is every seafarer’s nightmare. Should it occur in
a confined area, like a channel or a strait, where the traffic is heavy, several as well as
serious risks are likely to be faced.

On the other hand, a major shipping accident becomes even more critical by way of, say,
water ingress thus possibly worsening the ship’s damage stability if exacerbated by heavy

    In rounded figure, 4/5th of the world trade.

    According to Lloyd’s Register’s Casualty Statistics, the number of ships lost as a proportion of the number of ships in the world fleet continues
     to decline:
                   In 1995, 3 ships were lost for every thousand in the world fleet.
                   In 2000, the equivalent figure was 1.9 for every thousand.
    Major studies into marine oil spills show a similar decline in the annual percentage of oil carried by ships that is subsequently spilled.
weather or strong current. In some other accidents however the issue becomes more
“environmental” due to oil spillage. (Akten and Gonencgil, 2002)

The reasons for shipping accidents are many and complex. Increased sizes of ships to
achieve economies in transport costs are one of the primary reasons. Bigger size brings
corresponding increases in cargo and passenger capacity; hence when a casualty occurs, the
risk of life and property immediately becomes higher. Reduced ship maneuverability in
connection with larger scale, which ultimately is a function of increased risk, is another
contributing factor in marine accidents. (Chapman and Akten, 1998)

There may be several causes for shipping accidents. In broad terms these are: natural
conditions, technical failures, route conditions, ship-related factors and human or personal
errors.
         Natural conditions could be natural phenomena such as current, tide and tidal
         stream, severe wind, reduced visibility (fog, heavy snow and rain), storm seas,
         darkness etc. affecting the ship or those controlling her.
        Technical failures are shortcomings within the ship, such as corrosion3, steering
        failure, engine failure, or hull failure arising from defective materials or
        construction, or by the shore-based installations, such as aids to navigation.4
         Route conditions may include navigational error like over reliance on inaccurate
         nautical charts, charts of suspect reliability or based upon old surveys, narrow
         channels with abrupt and angular windings, allowing for very limited
         maneuverability and exposed to dense marine traffic, such as the Turkish Straits,
         anchorage contiguous to traffic separation lanes, confined marine areas with
         insufficient sea-room as well as navigational hazards such as shoals, reefs, wrecks
         etc.
         Ship-related factors could be the weakness of a ship, associated with her larger
         size, hence less maneuvering capability and stability or draught constraints.
         Human errors may include, inter alia, a lack of adequate knowledge and
         experience, technical inability, bad look-out, not paying proper attention to
         procedures and rules, carelessness in commanding a ship, misinterpretations of
         radar information, fatigue and lack of alertness, overworking, tiredness,
         insufficient rest periods, etc.
         Cargo-related factors mostly include dangerous goods and heavy cargoes; i.e. their
         hazardous characteristics (oils, chemicals, nuclear substances), the place /
         compartment they are stowed onboard ships (on deck or under deck), and degree of
         diligence that such cargoes need (grain, timber), all of which are related to ships’
         seaworthiness.

Most of the accidents are attributed to human error; quite a lot to bad weather conditions
and some also to force majeure reasons.

“Even on the most modern ship, the most sophisticated navigational instrument is still the
human being, and one of the problems could be that those human beings are starting to rely
too much on particular pieces of equipment and not enough on their own common sense,
experience and training (O’Neil, 1999)

    Corrosion has been a major factor in bulk carrier losses.

4
    Some of the navigation and collision avoidance aids such as ARPA,GPS and VHF may also contribute to the cause of a collision accident if not
     treated properly or the correct precautions are not taken.

                                                                                                                                               2
Any accident may have more than one cause. Nevertheless, statistical analyses on the basis
of the main causal trends explicitly reveal that human errors, though declining marginally,
continue to be the major cause for all shipping accidents - being almost 80 percent. In other
words, “the acts or omissions of human beings play some part in virtually every accident,
including failures, like structural or equipment ones, which may be the immediate cause.”
(ISF and ICS, 1996)

The density of vessel traffic, particularly in those narrow areas such as straits, channels,
port approaches where there is insufficient sea-room, close-quarter situations frequently
exist, and more ships are concentrated, remains second to human errors as contributing
factor of marine casualties.

Shipping accidents by types are quite many and their effects on marine environment differ
from one another. Collision or contact, capsize, foundering, breaking up, grounding,
breakdown of the ship underway, stranding, and fire or explosion are examples of common
shipping accidents.

Collision is one of the major types of shipping accidents.It is the impact of ship against ship
by way of striking or contact. Ships or other floating bodies are the main constituents of the
collision cases. Such accidents have still been the bane of modern navigation - despite the
sustained improvements in navigation techniques.

There are even certain collision accidents and claims which taken in the past to the
International Court of Justice for final resolution. The first such marine collision dispute in
the World is the Bozkurt v. Lotus case.

On the night of August 02, 1926 the Turkish cargo ship, Bozkurt, with 1000 tons of coal
onboard was involved in a collision in the Aegean Sea, off Sigri Lighthouse, west of Lesvos
(Mitylene) Island, with the French passenger ship, Lotus. The Bozkurt sank just after the
incident and only 10 seafarers out of the full complement were rescued and eight of the
crew was lost.

The case was brought to the attention of the Turkish criminal court and on appeal the
Court found that both parties contributed to the collision and accordingly both vessels were
held liable. The decision that each vessel should have proportionate share in the blame plus
criminal penalties was upheld.

The French side raised objections against the Court decision that the Turkish jurisdiction
on the case was inconsistent. The Court decision was jointly appealed through the
International Court of Justice, in Hague, and the International Court finally upheld the
Turkish Court decision.
The main question before the Court whether Turkey had acted in conflict with the
principles of international law by instituting proceedings against the master of m.v Lotus.

The Court decided in its judgment of September 7, 1927 that Turkey had not acted in
conflict with the principles of international law.

Fire aboard ship at sea is one of a seafarer’s worst fears.It is also another serious threat
facing all seafarers and passengers which may result in considerable financial loss or
large-scale environmental damage. It sometimes lead to total loss of the ship and / or her
cargo.In spite of high safety standards it is an immediate danger for life,cargo and the
environment.


                                                                                               3
In the earlier days of merchant shipping a shipboard fire had been the major threat for
ships and seafarers. Today it ranks second to stranding accidents in shipping casualties. 5
(Mendiola et al, 1999)

Marine accidents include groundings and strandings, too. The tanker Torrey Canyon which
grounded off the Scilly Isles just 37 years ago was the first major incident of its kind
resulting in extensive oil pollution. The Norwegian tanker Orange Star went aground in the
Bosphorus in December 1997 in the same spot as the bulk carrier Friendly a year
previously. (Chapman and Akten, 1998) Similarly, the Greek tanker Sea Salvia with 81000
tons of Russian crude onboard and en route for the Aegean Sea, ran aground in July 1998
in the same point as the other Greek tanker Crude Gulf, loaded with 140800 tons of crude
of the same origin, almost a month after, on August 25, when both in the wrong shipping
lane at the southern exit of the Bosporus, even blocking the shipping movement for quite
some time to and fro the Haydarpasha container terminal.

The grounding of merchant ships may well result in fire and / or explosion particularly
when a large tanker involved in such an accident.


       2.   The Bosphorus : A study area with high accident rate

The Strait of İstanbul,or the Bosphorus, is one of the major and busiest seaways in the
world linking the Black Sea to the Sea of Marmara. It is a narrow “S-shaped” channel, open
for international shipping. The Strait separates the metropolitan area of Istanbul into two
almost equal parts and due to the over-crowded character of the area the consequence of
any marine casualty is potentially catastrophic. The city, with its 15 million inhabitants,
has so far been fortunate to have escaped relatively undamaged. (Chapman and Akten,
1998).

The Montreux Convention relating to the regime of the Turkish Straits establishes freedom
of passage and navigation with certain formalities for merchant vessels of any flag and with
any kind of cargo,by day and by night,and the Strait is kept open for shipping traffic.
Hence the Bosphorus serves as an international seaway of economic and strategic
importance.

 For the period 1994 – 2002 since the introduction of the TSS the mean of the yearly figures
indicates that 132 vessels a day (or nearly 6 vessels an hour) navigate the Strait. When
local traffic is taken into account, almost another 2000 crossings a day (or roughly 85
crossings an hour) must be added to this figure. Therefore, it wouldn’t be wrong to say that
any time of day nearly 100 “floating bodies” use the Strait – either crossing or proceeding
up or down.

The Strait with its dense shipping traffic is second to the Malacca Straits. The Straits of
Malacca are the busiest seaway in the World with approximately 300 vessels passage a day
(100.000 per year).The Bosphorus follows with an average of 132 vessels transit (passage)
a day, local traffic exclusive, and the Dover Strait with approximately 125 vessels passing
north-south and 100 crossings a day is the very close third. (Oral, 2001)

Similarly, shipping traffic compared with the main canals of the World shows clearly the
high density of the traffic through the Strait: (1999-2000)

In the year 1841 the number of transits was 4125 and this almost tripled in 1856 during
the Crimean War to 14170. Today there are around 24000 transits in each direction
including inter alia, large tankers, chemical product tankers, LNG and LPG carriers as well
as local transits. In 1936 when the Montreux Convention was signed and brought into
effect, the number of vessels passing through the Bosphorus was 4700; the aggregate
tonnage was 9.71 million tonnes and the average vessel size was 2066 nrt. Similar figures
for 2002 were 47253 vessels with an aggregate tonnage of 389.4 million tonnes and an
average vessel size of 8300 grt. 6

The Bosphorus is the one of the most critical passages in the world for vessels particularly
because of its narrowness, its shape with several sharp turns and headlands which limit
the opportunity to maintain to a proper look-out and the complex nature and changes of its
currents.

Currents and darkness are the two dominant factors causing marine accidents in the
Bosphorus. The complex and day-to-day changing character of the prevalent surface
current, as well as the large course alterations that vessels have to make with or against
the main current, cause the difficulties. Most of the incidents occur when vessels travelling
with the current taking sharp turns lose their manoeuvrability. There are critical areas in
the Strait,such as Yenikoy and Umuryeri (or Umur Banki) where most of the stranding
and grounding accidents occur as vessels negotiate sharp turns (80º at Yenikoy, 70º at
Umuryeri). More than half of the grounding and stranding incidents in the Bosphorus
since 1994 in which the Traffic Separation Scheme (TSS) was introduced have occurred at
these two critical points. Specifically, 26 such casualties took place in Yenikoy and
Umuryeri areas (13 in Yenikoy, 13 in Umuryeri) out of the total 45. (Akten, 2004)

A total of 461 marine accidents of different types (i.e 209 collisions, 138 groundings, 77
strandings, 28 fires / explosions and 9 others, such as rudder blockage, vessel’s list, or
engine breakdown) occurred in this tricky strip of water during the period 1953-2002,7 the
majority being collisions. Since 1994 when the TSS was introduced there have been 82
marine casualties the majority of which have been groundings / strandings. Groundings
and strandings having occured in the Bosphorus constitute 55 percent of all casualties with
the major risk factors being currents, sharp turns and darkness.

                                                                                                                                            5
Over the last 10 years the Turkish Straits have turned into one of the key shipping foci of
the world seaborne oil trade, comparable with the Suez Canal, the Straits of Malacca and
the Straits of Dover. It was previously the same in 1892 when oil cargoes loaded in the
Black Sea port of Batumi were delivered by tankers which passed through the Turkish
Straits to their customers in the Far East. Nearly 123 millon tons of oil passed through the
Turkish Straits last year, representing 5 per cent of the oil traded by sea.8 The number of
tankers passing through the Strait of Istanbul last year was 5188.9 In other words, 15
tankers per day, large or small, laden or in ballast, sailed through the Bosphorus.
Similarly, a further 1330 tankers carrying LPG and chemicals used the Bosphorus, an
additional 4 tankers a day - but smaller in size.

Geographical and oceanographic conditions as well as navigational constraints are the
main parametres making the navigation through difficult and risky.Additionally, since
passage through the Strait entails a run by about 17 nautical miles all the way and takes
almost two hours, utmost vigilance is necessary in order to maintain safe standards of
navigation and to conduct vessels.
Safe navigation in the Bosphorus is a matter of vital importance to Turkey as well as to all
nations using the Strait. Therefore, the dangers posed by ever increasing shipping traffic to
the surrounding inhabited areas and to the environment have compelled Turkey to take
immediate action and to reinforce existing regulations of maritime traffic in the Strait.




                        Vessels proceeding without a pilot,
                        Dense marine traffic,
                        Bad weather conditions,
                        Technical inadequacy of ship,
                        Complex and sometimes day-to-day changing nature of currents,
                        Lack of adequate knowledge about the region,
                        Loss of alertness and caution impeding the safe passage,
                        Existence of areas with sharp turns (45º for Kandilli, 80º for Yeniköy, 70º for
                        Umur Bankı),
                        Lack of a proper vessel-escorting system.


          2. Safer shipping ahead?
          2. Acident-free shipping: a dream?

Very many vessels differ from one another in size and types navigate round-the-clock on the
seven seas. On their way to destinations they normally follow customary routes and
courses; the primary objective along the way being, inter alia:
       to keep the shortest possible distance,

8
  Corresponding figures for previous years in terms of million tons was as follows : 61 in 1997 , 67 in 1998 , 85 in 1999 , 91 in 2000 ,
  101 in 2001, 123 in the year 2002 respectively.
9
  Figures for number of tankers passed through for previous years was as follows : 4248 in 1996, 4303 in 1997, 5142 in 1998, 5504 in
  1999, 6093 in 2000, and 6516 in the year 2001.

                                                                                                                                           6
       to avoid navigational hazards, and defective navigational marks, and,
       to prevent collision(s).

In areas where shipping traffic exists, encounters of vessels, be it seldom or frequent, single
or multi, take place if and when their courses coincide and maneuvering may become,
sooner or later, inevitable.

Areas of heavy traffic, vicinity of large ports or port terminals, headlands where traffic vice-
versa are concentrated are the critical places that likely collision accidents to occur.

Ships spend quite long periods from one port to another, are exposed to various external
hazards such as darkness, different visibility conditions, etc. which one way or another
contribute to shipping accidents like collisions. Bad look-outs, not taking the proper action
until a very late stage, close presence of a third ship which prevents taking early action and
a late proper maneuver as against the crossing, overtaking and meeting end-on rules, etc.
also constitute the internal threats of collision incidents.

The risk of collision for a vessel proceeding on a shipping route singly is almost zero. If,
however, there is another vessel underway in the area even a simple encounter may create
risk of collision if the Collision Regulations are not adhered to and / or can have disastrous
outcome.

Should vessels underway approach one another so as to involve risk of collision either of the
following encounter situations may occur:
       a. meetings,
              end-on or nearly end-on as to the other,
              crossing on either side, or
       b. overtaking the other.

Where one of the ships involved in a collision accident is a tanker, or a vessel carrying
dangerous goods, the outcome will be damage to the environment. Incidents have occurred
in the Turkish Straits, such as with the Peter Zoranic, World Harmony, Norborn, Nordic
Faith, Blue Star, Lutsk, Independenta, Nassia, Jambur and Datton Shang to mention a
few, are examples of this. Around 200.000 tonnes of oil has been spilt into the Strait of
Istanbul and its approaches from these collisions alone. (Chapman and Akten, 1998)

Accidents may take place anywhere, anytime and under any conditions – day or night, in
clear weather or restricted visibility, in narrow straits, canals, inland waterways, coastal
waters or on the high seas; and even due to defective or off-station navigational marks.

In daytime and in a visual situation, it is easier to judge distances. Likewise, course
alterations are rather obvious and the other vessels around will notice any change of
aspect. To judge distances and to estimate the visibility at night is at times quite difficult.
Therefore, navigation, even on a dark clear night, requires special care for certain reasons
such as:


       areas where there exist bright and scattered background lighting from the shore
       can cause confusion, and,
       reduction of the nominal range of visibility of the lights thereby, and,
       sailing lights being hardly visible,
       unlit navigational hazards affect also the navigational safety.

                                                                                              7
These reasons are also contributing factors in shipping accidents.

It has been computed, for instance, that the lights exhibited on both sides of the Strait of
Istanbul are visible only to 1.9 nautical miles at night though their nominal range is mostly
eight nautical miles, due to the presence of bright background lights from restaurants, city
and residential illuminations, moving cars, etc. Nevertheless, the background lighting in
the Strait usually masks the navigation lights of not only small crafts but also large vessels
and the presence of such floating objects are sometimes first noticed by the moving
silhouette they cast against the shore lights. (Akten, 2004)

Darkness is thus one of the significant impacts on clear weather accidents.

“The effect of darkness on the accidents in clear weather was found to be three times the
number taking place in daylight”. “During restricted visibility there was found to be no
appreciable difference.”   (Cockroft, 1982) For the Bosphorus however the number of
accidents occurring in darkness was found to be nearly twice the number of occurring in
daylight. (Akten, 2004)

Vessels in the course of their movements may show day and night different aspects, from
port to starboard, stem to stern, etc. In the case where one vessel can be seen by eye from
the other and silhouettes are visible, their respective aspects may apparently be observed.
In all weathers from sunset to sunrise, within the hours of darkness and when silhouettes
are hard to see however, sailing lights the vessels exhibit help to identify their angle of
view.

Hence, sailing lights play a crucial role in order each vessel to ascertain the others’ way.
Any alteration of course, be it substantial or small, may readily be apparent to another
vessel observing visually her sidelights and masthead light(s).

The first introduction of a regulation requiring steam ships to carry compulsory sailing
lights goes back to late 1840s and is the outcome of the collision between the British ship
Arctic and the French steamer Vesta. The loss of the Arctic after the collision led to
compulsory red and green sidelights on ships. In the early days, it was customary to carry
a single light on the bowsprit end. (Lloyd’s List, 1984)

The rules concerning side lights and that a masthead light be carried onboard steam ships
was first incorporated into the Steam Navigation Act of 1846 in the year 1848, two years
later the Steam Navigation Act entered into force. However, it was in 1858 that sailing
ships were required to carry sidelights. (Sailing Depth-1, 2001)

Current rules require the navigation lights to be shown on vessels operating between
sunset and sunrise, and even from sunrise to sunset in restricted visibility. Green and red
sidelights, masthead light(s), stern light(s), flashing light and all-round lights to indicate
vessels not only by size (large or small, i.e less than 12 metres, or 50 metres or more, large
vessel, vessel constrained by draught, etc), but also the type and purpose (sailing vessel,
fishing vessel, tug boat, hydrofoil, etc). The navigation lights when observed visually from
the other vessel also indicate the aspect and the direction the vessel is heading, and give
clues with regard to any proper action to avoid collision - in particular course alteration,
slowing down or stopping the vessel.

 “From the safety and pollution prevention viewpoints, shipping is in a much better state
than it was a decade ago. Lloyd’s Underwriters Marine Intelligence Unit statistics show a
clear and sustained decline in the number of ships over 500 gross tons lost each year, from
over 180 units in 1991 to less than 80 units just ten years later.During the same period, the
decline in terms of aggregate tonnage lost each year is from 1.75 million gross tons in 1991
to less than 0.75 million lost in 2001.” (O’Neil, 2002)


       III. Conclusion

Safe navigation in the Bosphorus is a matter of vital importance to Turkey as well as to all
nations using the Strait. Therefore, the dangers posed by ever increasing shipping traffic to
the surrounding inhabited areas and to the environment have compelled Turkey to take
immediate action and to reinforce existing regulations of maritime traffic in the Strait. 10


The Montreux Convention with regard to the regime of the Turkish Straits establishes the
principle of freedom of navigation for all merchant vessels, regardless their sizes, flags and
cargoes, in peace time, with Turkey the sole authority with legal power to interpret the
Convention.This freedom for vessels does not however give free reign to uncontrolled or
undisciplined passage in accordance with the provisions of of the relevant internationally
accepted rules and regulations currently in use.




ABSTRACT

Casualties having involved large tankers in particular, have caused ecological disasters in
the past few decades. One of the most critical areas where incidents have taken place is the
Turkish Straits Region (TSR). The Bosphorus and its approaches with its 12 millions of
inhabitants have faced very many casualties. Under the current heavy maritime traffic, not
only the risks of collision increased but also impacts of a probable tragic disaster became
more likely. The Turkish Straits, particularly the Strait of İstanbul are exposed to dense
marine traffic. According to the statistics published by the Maritime Undersecretariat more
than 50.000 vessels per annum enjoy transit passage through the Bosphorus.

Dangers and environmental threats exist in the Bosphorus today due to its norrow and
confined character, ever-increasing international shipping traffic in the area and increased
dimensions of transiting vessels. Kargoes of hazardous and harmful character also
contribute for the increase of such threats. For instance, an LPG tanker of 30.000 t may
have an effect of 11 times more than that of the bombs dropped on Hiroshima and
Nagasaki.

In order to reduce risks as such the Bosphorus needs vessel-escording services be set up,
especially for large vessels carrying dangerous goods.

The most critical part of the Turkish Strait Region with regard to the risk of casualty and
environmental sensitivity is the Bosphorus itself and its approaches. As the Strait

separates the metropolitan area into two parts almost equally (i.e like river flowing in the
centre of a city) and due to over - crowded (almost one-forth of the population) character of
the area, consequence of any casualty is very likely to be a catastrophy. It is simply a divine
luck that the city with its 15 mio. inhabitants has so far escaped such a disaster encamped
relatively undamagedly.

A Crucial Safety Problem Arising From Maritime Traffic: Marine Pollution By Oil

1. Environmental performance of marine pollution

Marine pollution is defined by the Group of Experts as: “ introduction by man of substances
into the environment resulting in such deleterious effects as harm to living resource,
hazards to human health, hinderance to marine activities including fishing, impairment of
quality for use of seawater and the reduction amenities. Estuarine waters to fall within the
marine environments” (J.W. Smith: 1971). Marine pollution emanating from shipping
operations may either have one or some of the following sources: Oil, chemical and liquefied
gases, garbage, sewage, ballast water and dangerous goods.

Marine pollution, particularly by oil, is of great importance because the most important
pollutant in tonnage terms is oil. Oil is a general expression to designate a viscous liquid
having a density less than that of water. It can include crude oils varying in proportion, and
refined oils (such as diesel oil, heavy fuel oil, lubricating oil, kerosene and gasoline). Some
oils are toxic to marine life, others are harmful partly due to their smothering effect when
deposited (J.W. Smith: 1971).

Oil is the most important pollutant and pollution incidents are caused mostly either by ship
operations or tanker accidents, like collisions or groundings. The consequences of an
accident can have negative impact on the affected area, particularly if the accident occurs
close to the coast.

As oil floats on water it contaminates shores and floating objects and also renders water
and beaches unsuitable for recreation. As many pollutants which are soluble in water or
finally dispersed can not be recoverable; oil however, by floating on the surface grants the
possibility of being removed.

“More than 50 p.c of the cargoes carried by sea is said to be hazardous or harmful from
either safety or environmental point of view. Similarly, many materials used in the
operation of ships have the potential damage to environment.” (BIMCO: 1993).

In order words, the amount of oil entering the sea from shipping activities has lessened and
was estimated to have fallen from almost 1.57 mio tons in 1981 to roughly 569.000 tons in
1989. The figure for 1973 however, was 2.1 mio tons (BIMCO: 1993).

The credit for such a substantial positive impact is mainly due to the introduction of several
practices applicable to the shipping industry, particularly on tankers, such as load-on-top
and COW in cargo handling, separation and filtering devices for the ship-based discharge
coupled with SBT requirements by the technical regulations. The implementations we have
emphasized reduced operational and accidental pollution considerably.

2. Casualties with large scale of pollution




                                                                                            10
Increasing the dimensions of ships to an incredibly larger size for the good sake of
economies of scale, has brought in higher risks and ultimately more costly actions in case of
emergency. An example to this effect is the M.T. Atlantic Empress disaster, off Tabago, in
1979 when 276.000 tons of oil polluted the sea.

Casualties ended up with pollution have occurred within the Turkish Straits Region also
and around 200.000 tons of oil spilled into the Bosphorus and its approaches out of the
collision incidents which are listed in Table - 3.

The Independenta disaster, besides its fire and explosion threats to the İstanbul area also
added a new but serious dimension to the environmental performance, namely the air
pollution. The emission of SO2 NOx and particles given to the atmosphere were equal to
the daily emission of the whole city in winter. In the six days period almost 480 tons of SO 2
and 104 tons of NOx were emitted to the atmosphere in that area. It is clear that emissions
had an impact on the acidic rains measured regionally, as a consequence of emissions and
particles being carried to quite remote distances (F. Ertürk: 1994).


How about if an LPG Casualty Occurs?




                                                                                                11
Dangers and environmental threats did not exist long ago; but it does today. There have
been occasions when the strait was even bloced off for navigation considering the safety of
Istanbul. Such an international seaway, granting freedom of navigation for any flag and
vessel, measures for environmental safety are of prime importance for the inhabitants of
İstanbul. An LPG tanker of 30.000 t may have effect of 11 times more than that of the
bombs dropped on Hiroshima and Nagasaki. The Bosphorus is disastrously faced with
many such dangerous vessels passing through almost every day.

Nothing is impossible; someone might argue that an LPG vessel is safe enough and has no
risks and petroleum gases carried in tanks do not explode easily; but it can not be measured
beforehand how physical changes can easily give rise to a violent collision ending up with a
very serious threat or how a large fire affects the gas leaking or escaping from a tank...
Without jumping into chemical equations one can calculate the energy emitted due to
successive explosions in an LPG tanker of 30.000 tons.

Lower heating value of the LPG carried in tanks:
      QLPG (total) = 30.000.000 kg x 40.000 KJ/kg = 1.200.000.000.000 KJ

As 1 kg of dynamite generates energy of 5434 KJ;
       1.200.000.000.0 KJ : 5434 = abt. 220.000.000 kg of dynamite = 220.000 tons of
          dynamite.

The atomic bombs dropped to Hirosima on Aug. 5, 1945 was equal to 20.000 tons of
dynamite (İ.Doğru: 1989). Therefore an LPG tanker of 30.000 tons size can generate energy
equivalent to approximtely 11 atomic bombs of Hiroshima size.

Certain rules and regulations that internationally acceptable have been set up as an
operational guidance to assist the personnel serving onboard either to improve or to
maintain safety at a certain level. This does not mean that no emergencies can occur
affecting the environment. No one can expect millions of inhabitants be prepared for the
immediate action to be taken in the event of an emergency arising from an LPG tanker
while enjoying the freedom of navigation through the Bosphorus. Flammability as well as
toxicity are the main hazards of LPG on environment.

The human body can tolerate gas concentrations up to 0.2 p.c and irritation of eyes occurs.
When the concentration reaches to a level of 0.7 p.c however, drunkenness within 15
minutes takes place and immediate death happens when the concentration is of 2 p.c or
20.000 ppm (ICS, OCIMF and IAPH: 1984).

Another aspect of LPG in case of gas escaping or leakage is the toxicity. As specified in the
safety guide, petroleum gas produces narcosis on human being. “The symptoms include
headache and eye irritation with dizzines similar to drunkenness. At high concentration
these lead to paralysis, insensibility and death” (ICS, OCIMF and IAPH: 1984).

IV. CONCLUSION

Shipping accidents of today have become more “environmental” and the issue has been
though than ever for all parties concerned.

Potential risks and perils already exist in the Bosphorus mainly due to increased
dimensions of transiting vessels as well as their cargoes of hazardous or harmfull character.
Luckily, people living in the area have not been affected that much and perils were avoided


                                                                                           12
with minimum damage. But the Bosphorus, as very sensitive environmental area and full
of culture, history, beauty and nature, has to be protected for coming generations by way
implementing safer navigation procedures thus improving innocent passage and avoiding
transitters having a lack of experience on the area to navigate through unless guided.

V. DISCUSSION

The Turkish Straits, especially the Bosphorus need, the help of vessel-escorting services in
order to reduce risks of casualty for large vessels. When a vessel loses her navigational
control due to technical or human malfunction, or external factors such as wind, current,
eddies etc., or vessel’s shape like ro/ros and car carriers struggling with heavy drift because
of their huge air draft, all of which affect proper underway one way or other, vessel
escorting is inevitable.
Active escorting of vessels carrying hazardous cargo is the key remedy for safer navigation
in narrow waters.
Main objective for vessel-escorting is to retain control of the vessel escorted and thus to
prevent collision or grounding by keeping her on the planned course or to stop her
when/where necessary.
Although there exists such service in the Bosphorus rendered for vessels, it is hard to say
that the system as it is today is adequate to meet ever increasing demand on-the-spot.

Major Oil Spills
  The table below gives a brief summary of 20 major oil spills. A number of these incidents,
  despite their large size, caused little or no environmental damage as the oil did not impact
coastlines, which is why some of the names will be unfamiliar to the general public. The Exxon
Valdez is included because it is so well known although it is not the twentieth largest spill of all
                                time but rather about number 34.
